An adopted son of convicted child molester Jerry Sandusky is providing details of the alleged sexual abuse he suffered at the hands of his father.

Matt Sandusky, who was initially a foster child of the Sanduskys, tells Oprah Winfrey in a TV show airing Thursday night that his overnight visits with the family as a child were good "except for one part, bedtime."

At bedtime in the Sandusky's home in State College, he said, Jerry Sandusky's "ritual began."

"The overnight visits were -- they were good. I mean, except for that one part, bedtime. Bedtime was the bad part. But any other time that we were in the home, that we were doing anything in the home with the family, it was fine and it was -- again, you would look at that family and you would say, wow. Like I wish that I had brothers and sisters that cared about me. I wish that I had a mother who cooked dinner every night for the whole family. I wish that I had all of these things. But then at bedtime, his ritual began," Matt Sandusky told Winfrey in a brief clip released by the network.

The network said Sandusky discusses the grooming, methodical control and manipulation he faced as a child.

Women who were sexually abused as children are more likely to show the earliest signs of heart disease in their 40s and early 50s, researchers said Thursday....

Examining the health histories of 1,400 women ages 42 to 52, the researchers discovered those who suffered sexual abuse had thicker inner linings of their arteries, something doctors call intima-media thickness, or IMT. That thickness can lead to atherosclerosis, a buildup of plaque, and eventually blockage. About 14 percent of American children are victims of some kind of abuse, according to the Centers for Disease Control and Prevention. In this study, the rates were higher: "About 16 percent of the women reported a history of childhood sexual abuse, across all racial groups, with the abuse as high as 20 percent among African-Americans," the researchers reported....

But the new paper in Stroke found trends that couldn't easily be explained. For one, women who reported suffering non-sexual child abuse weren't any more likely to have IMT than those who were not abused. And, oddly, cardiovascular risk factors like obesity and high blood pressure were not predictors of IMT. In other words, abuse victims who were otherwise healthy still showed the higher rates of IMT.
